While creating bank master data through T.code FI01 system will consider bank key as bank number but for one bank system is not consider bank key as a bank number.
The bank number is not in editable mode due to that i am not able to do anything in change mode. We can achieve the same through table entry but client is not accepting for that.
For APP purpose we need to maintain bank master data in Vendor-General data-Payment transaction.
Can some one help me how we can input or change bank number in bank master data(House bank is not created for this).
